This was quite thorough with a high detection rate the program located all the sample threats on the test, although we did experience a few false alarms that got set off from legitimate downloads. We were hardly disappointed though, and appreciated that even a deep scan was quite fast and completed in only 50-75 seconds. Our scan times exceeded the claimed 20 seconds on their website, with even the fastest option measuring a significantly longer 50 seconds when we tested it. Webroot buries these options so deeply in its interface that you might not figure out these options are here, as you have to head to PC Security > Settings > Custom Scan to find them.
There are options among the scan types, that include a quick scan of the RAM only, a full scan of the local hard drives, a deep scan that searches for rootkits, Trojans and more, and a custom option to target a scan on specific files or folders. You can launch a simple scan with the extra-large Scan My Computer button, or via a right-click on the Webroot system tray icon. However for the most part Webroot is quite straightforward to use. Webroot SecureAnywhere AntiVirus has a complicated interface at first glance, with many panels, buttons, switches and icons.
Combined they only consume just under 10MB of RAM, which is pretty minimal on a modern PC. Webroot merely adds two additional background processes on our test system, with the first a user application, and the second a service. Even with older PC systems, Webroot has minimal impact on system performance.
